Main application.
This instrument is suited for all kinds of borehole tests under the harsh conditions in underground coal mines, and able to implement the hole wall imaging、video recording、image capture and zoom in on particular sections of image etc. It is primarily used to observe the occurrence and development of fault fissures, water-bearing structures、cave cavern and position of aquifer outlet. It also able to observe the direction、thickness、inclination dip angle of the coal seam and other ore bodies, and distinguish ore body, rock mass, coal seam, soil layer and other geological structures.
Main features.
This equipment uses Android system software development.
It includes borehole image acquisition and storage、video acquisition and storage, borehole trajectory, depth measurement, expand and mosaic of image, and other functions.
